Materials researchers at the Swiss Paul Scherrer Institute PSI in Villigen and the ETH Zurich have developed a very simple and cost-effective procedure for significantly enhancing the performance of conventional Li-ion rechargeable ...

Accident investigators are recommending the U.S. government require air shipments of rechargeable batteries be separated from other flammable cargo to prevent uncontrollable fires that can destroy planes.

Led by the inventor of the lithium-ion battery, a team of researchers in the Cockrell School of Engineering at The University of Texas at Austin has identified a new safe and sustainable cathode material for low-cost sodium-ion ...

One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle—sometimes doubling in volume, and then ...

An advanced manufacturing approach for lithium-ion batteries, developed by researchers at MIT and at a spinoff company called 24M, promises to significantly slash the cost of the most widely used type of rechargeable batteries ...

To overcome the danger of fires and increase the energy density of lithium batteries, researchers are developing solid-state lithium batteries that replace flammable liquid electrolytes with a safer solid electrolyte. These ...
